I ran home from work at lunchtime to pick up some coral that had been shipped and decided to inspect our 20g. I was looking for our BT and could not find him, then I looked at the top of the tank and he had wedged himself behind the heater and cooked himself. I pulled him out and did a quick 10% water change to pull some of the free floating pieces out of the water. Thank god I ran home from work or we would have lost the whole tank. Does anyone sell BT that have taken an IQ test? :'(
